Abstract

The invention relates to an aircraft provided on either side of its fuselage with at least one lift structure constituted by at least two wings whose distal ends are connected either to each other or to at least one wing element, each structure forming in front elevation of said fuselage a closed polygon, and comprising an upper wing and a lower wing, the zone of attachment of the latter on the fuselage possibly being offset in the direction of the streamline flow with respect to the zone of attachment of the upper wing. According to the invention, each of the wings is made so that the values of the moment of inertia and of the lift, both varying as a function of the longitudinal distance, each take a maximum value at a zone of the wing other than the root. The invention is more particularly applicable to aircraft with multiple wing elements.
